Abstract
Rotor (1) für Wirbelstrombremsen zum Bremsen von Wellen bzw. Achsen oder Antriebe jeglicher Art, bestehend aus zwei benachbarten Magnetscheiben (la, lb) und einer Rotornabe (2). An der Innenseite der Magnetscheiben sindjeweils Kühlrippen (4, 5) in langer und kurzer Ausfiihrung angeordnet. Die Rotornabe ist über Verbindungsstege (3) mit den Magnetscheiben untrennbar verbunden. Die Verbindungstege wiederum sind mittels mehreren gegengerichteten Bögen so geformt, dass bei Erwärmung des Rotor eine Art Federwirkung entsteht und dadurch bei unterschiedlichen Ausdehnungsunterschieden zwischen den Magnetscheiben und der Rotornabe keine unzulässigen hohen Thermospannungen entstehen. Zudem weisen die Verbindungsstege (3) und die Kühlrippen (4, 5) Spalte (6, 10, 13) auf, um eine, durch Thermospannung erzeugte zueinandergerichtete Verformung der Magnetscheiben spannungsfrei zu kompensieren.
